Study on the Bagasse Degradation by Cellulalse Producing Strain Penicillium sp. T24-2 and Hydrogen Production using Saccharification Mixture

Abstract

能源结构亟待从以石化能源为主的模式向以可再生能源为主的模式转变。纤维素生物质是自然界中最丰富的可再生资源,为未来大规模制备生物燃料提供了丰富的原料。本研究对产纤维素酶株菌的产酶或糖化条件进行优化,以提高纤维素的分解和糖化效率,实现对纤维素生物质的资源化利用。选用了实验室筛选的两株产纤维素酶菌株,进行了单菌株与双菌株混合固态发酵产酶及糖化实验,并利用产氢菌对糖化液进行发酵制氢研究。 青霉(Penicilliumsp.)T24-2能利用甘蔗渣进行固态发酵产纤维素酶。对青霉T24-2制曲的蔗麸比、曲酶糖化时间、加水比和曲料比等影响糖化效率的因素进行优化。确定了该菌株制曲的合适蔗麸比为4:6;曲酶糖...The energy consumption of world will change from fossil fuel-based model to a renewable energy-based model. Cellulosic biomass is the most abundant renewable resource on the earth. To comprehensive utilization of cellulosic biomass, the cellulase production and saccharification of Penicillium sp. T24-2 and Aspergillus glaucus EU7-22 were studied in this research. The cellulase production by solid...学位:理学硕士院系专业:生命科学学院生物学系_植物学学号:X20042600
